The World Health Organization currently recommends that school-based deworming programs include health hygiene education as a complementary measure. However, the sustainability and long-term impact of such hygiene education had yet to be assessed. In July 2012, this cross-sectional study was conducted in 18 primary schools in the Peruvian Amazon to gauge continuing adherence to a health hygiene education intervention introduced 2 years earlier to reduce soil-transmitted helminth infections. Due in large part to high teacher turn-over, only 9 of 47 (19.1%) teachers were still implementing the intervention. Health hygiene education interventions must, therefore, be designed to ensure sustainability in order to contribute to the overall effectiveness of school-based deworming programs.

Objectives. To determine the efficacy of single-dose albendazole (400 mg) for soil-transmitted helminth infections (STH) in schoolchildren living in one community of the city of Iquitos, Perú. Materials and methods. Within the context of a randomized controlled trial performed in a peri-urban community of limited resources located in Iquitos in the Peruvian Amazon, stool specimens were collected from Grade 5 schoolchildren in 18 schools and analysed for STH prevalence and intensity. A total of 1,193 school-age children were then dewormed with single-dose albendazole (400 mg). Of the 909 children who were found positive with at least one STH infection, a random sample of 385 was followed two weeks later when a second stool specimen was collected and analyzed. Results. The efficacy of albendazole was satisfactory: for Ascaris lumbricoides , with an egg reduction rate (ERR) of 99.8%; (95% CI: 99.3-100); for hookworm, with an ERR of 93.6 %; (95% CI: 88.2-96.6) and, for Trichuris trichiura, with an ERR of 72.7 %; (95% CI: 58.5-79.1). Conclusions. These results are consistent with previous data published on the efficacy of albendazole and the directives of the World Health Organization. Future research should focus on improving the efficacy of the treatment strategies for Trichuris trichiura infection.

OBJECTIVE: To investigate the effect of a two-component intervention to change hospital practice with regard to the timing of umbilical cord clamping. METHODS: A pre-/post-study design was used to measure the effect of a two-component intervention on mean time to clamp the umbilical cord. The study took place at Hospital Iquitos "César Garayar García" in Iquitos, Peru. A total of 224 women were recruited from the hospital labor room: 112 pre-intervention, from 18 May-3 June 2009, and 112 post-intervention, from 6-20 July 2009. The intervention consisted of 1) a "best practice" three-day training workshop on birthing, and 2) a hospital directive. All deliveries were observed and the time between delivery of the first shoulder and clamping of the umbilical cord was measured with a digital stopwatch. RESULTS: The mean time between delivery and cord clamping before the intervention was 56.8 seconds (95% confidence interval [CI]: 51.0, 62.7). This increased to 169.8 seconds (95% CI: 153.8, 185.8) following the intervention. The difference in mean time to clamp remained significant in multivariate analyses (βadjusted = 113.2 seconds, 95% CI: 96.6, 129.9). CONCLUSIONS: Hospital policy and practice can be successfully changed from early to delayed umbilical cord clamping using a simple, two-component intervention.
